Has anyone been on Mirena and had it taken out because it didnt agree with them and then been put on Implanon, (the needle thingy in your arm?) My GP wants me to go on this but as I understand it's all the same artificial hormone (namely Progestogen ) that's being released into your body so surely it will have all the same side effects?? Really don't want to go through all this again and beginning to think Hormonal Contraception just not for me. Hate the thought of sterilisation for either me or the dh though so not sure what to do.
